Altered Carbon

Founded in 2018, Altered Carbon develops ultra-sensitive, super low-power, miniature and cost-effective graphene-based gas sensors. Altered Carbon is based at the Bristol Robotics Laboratory, located at the University of West England (UWE).

The gas sensors are designed for a wide range of cases and applications however the Internet of Things (IoT) applications such as healthcare, food freshness monitoring and air quality are what Altered Carbon are focused on.

The sensors utilise the properties of the wonder material, graphene. It is the world’s only man-made 2D material with remarkable properties such as high conductivity, huge surface area and being essentially inert.

Despite a lot of hype and lab attempts by a variety of other companies trying to attempt to shift graphene gas sensors into market-ready products, the progress has been limited. This makes Altered Carbon one of the leading companies in the world with commercially viable graphene sensors.

Altered Carbon gas sensors are designed to detect nitrous oxide with the following features and benefits:

  • Ultra-low power
  • Sensitivity range: 20 ppb to 5 ppm
  • Response time: <1 second
  • Recovery time: 2 seconds to 2 minutes
  • Optimised for 1-3 years
  • Mechnical shock distant
  • Mid-range cost in low volume; low cost in very high volume
  • Good temperature range: up to 100°C
